UVA-CM treatment itself did not alter cell viability; however, UVA-CM treated bystander cells were more resistant to the lethal action of UVA, UVB, UVC or H<sub>2</sub>O<sub>2</sub>. Effects of UVA-CM on cell proliferation, mechanism of cell death, DNA damage, malondialdehyde formation, generation of reactive oxygen species (ROS) and antioxidant status were studied in A375 cells. We observed that UVA-CM triggered antioxidant defenses to elicit protective responses through elevation of antioxidant enzyme activities in cells, which persisted until 5 h after exposure to UVA-CM. This was possibly responsible for decreased generation of ROS and diminished DNA and membrane damage in cells. These bystander cells were resistant to killing when exposed to different genotoxic agents. Damaged nuclei, induction of apoptosis and autophagic death were also lowered in these cells.
